Hi,

• IS INITIAL Means NO Records.
• IS NOT INITIAL Means 1 or more than one records.

Example:

SELECT TKNUM
INTO TABLE @DATA(LT_VTTK)
FROM VTTK WHERE TDLNR IN S_TDLNR .



IF LT_VTTK IS NOT INITIAL. "If record/s found from above table then
WRITE : 'Shipment Number Found'.
ELSE. "If Not Found
WRITE : 'No Data Found'.
ENDIF.
*******************OR*******************
IF LT_VTTK IS INITIAL. "If NO record/s found from above table then
WRITE : 'No Data Found'.
ELSE. "If any record/s Found
WRITE : 'Shipment Number Found'.
ENDIF.

IS INITIAL : is equal to its "initial value" (depends on type)

IS NOT INITIAL : is not equal to its "initial value" (depends on type)
